On the Bassac river, rafts of water hyacinth floated in the midstream current, pursued by rumbling barges and spluttering long-tailed boats vying for open water.

Fishermen stood on the prows of their narrow skiffs, casting nets into the late-afternoon breeze, disturbing the reflections of the setting sun.

Close to the Cambodian border in southernVietnam’s Mekong Delta, the Bassac is overlooked by the town of Chau Doc.

I’d travelled there earlier in the day by road from the central Mekong Delta district of Can Tho, and I needed to stretch my legs.

Along the town’s corniche, paunchy middle-aged men jogged, a children’s karate class practised kata to the count and a circle of young men competed to keep a wicker ball airborne to the amusement of a trio of admiring girls.

Following the path as it left the river’s course, I entered a market street where densely packed stalls were already being tidied away, the throng of shoppers and scooters separating to reveal soupy organic pools amid the cardboard and plastic flotsam of a day’s trading.

At a modest open-fronted bar, a television held customers in the thrall to some dubbed Chinese historical drama.

I sat down at one of the bar’s metal tables and ordered a Saigonbeer.

A second bottle arrived along with Qan, a wiry and intense cyclo-taxi pedaller.

“I wasn’t born here,” he told me.

“Born in the country.

Something different, not buildings like this.”

He pointed at several five- and six-storey blocks. “I rent a room for me and two kids.

In one month, 20 days bad, 10 good.

If I earn 250 dollars [approximately £160] then I have extra money.”

It might have sounded like a hard luck story angling for a beer but something about Qan’s delivery made me hesitate.

“I sometimes carry seven people, like you maybe four…”

He lit a cigarette and asked my age, surprised when I told him I was almost 46.

“I’m 40, I thought you were the same age.”

He was quiet for a while, perhaps contemplating my easy life.

I paid my bill, included a beer for Qan, and left.

It was dark now.

Behind closed and covered market stalls an old man stood holding court to an assembled group and lit a roll of newspaper.

The group watched as the torch was waved and the flames grew.

Suddenly, firecracker snaps erupted from the paper, sending sparks through the gloom.

After a moment’s silence, the group laughed loudly.

Farther along, other men sat in rows five deep, their faces lit by a football match on television; on an island of boxes a family chatted loudly and drank rice wine.

In Ho Chi Minh City, I dumped my bags, hailed a motorcycle taxi and melted briefly into the seething streets of scooters.

I was heading for lunch at The Rex Hotel.

At its rooftop bar, one-time haunt of GIs, politicos and war correspondents, I had lofty views over District One.

Below, the opera house, Notre Dame cathedral and City Hall were bordered by traffic-clogged thoroughfares, all these landmarks spectators as Vietnam’s tumultuous recent history unfolded.

At street level, a block away from the Rex Hotel, Graham Greene designated the Hotel Continental the haunt of noisy Americans; but it was here that he stayed when crafting intriguing tales of quiet ones, too.

Risking death by a thousand small motorcycles, I crossed the road and wandered through a side door, finding the hotel almost deserted, staff consumed by preparations for a pharmaceutical conference.

How times have changed.

Is Vietnam your average one-party Communist state?

Undoubtedly not.

The country’s new economy has been wholly embraced and in some places such is the free-market transformation that it’s easy to mistake images of Ho Chi Minh for those of Colonel Sanders.

The same can’t be said of political reforms, but there is a palpable atmosphere of energy and optimism.

As new direct flights with Vietnam Airlines to Ho Chi Minh City and Hanoi have simplified travel and shaved hours from journey times, it’s a good time to discover that Vietnam is a country and not a war.
